Description
In local-catalog mode, the reason of table metadata loading is logged as "needed by coordinator". It'd be helpful to tag the logs with the query ids. So we can confirm which query actually triggers metadata loading on the table.
Here are the catalogd logs for a REFRESH statement in local-catalog mode. The first part is loading the metadata of the table triggered by the planning phase in the coordinator. No query ids are tagged in this part. The second part starts with the resetMetadata request. Logs are tagged with query ids. That's what we want.
